We're dividing 409962 by 79 
The aim is to understand the frequency of 79 in 409962.

On to step 1:
4 divided by 79 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 79

On to step 2:
The number 79 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 79

Step 3:
If we divide 409 by 79, we get 5 and a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 395 from 409 and we're left with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 79

On to step 4:
If we divide 149 by 79, we get 1 and a remainder of 70.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 79 from 149 to get 70.
Append the next digit (6) from the dividend to 70 and continue with: 706 / 79

Let's proceed to step 5:
The number 79 fits into 706 8 times, leaving a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 518.0
Subtracting 632 from 706 leaves us with 74.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 79

Step 6:
When dividing 742 by 79, we get 9 with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 5189.0
Subtract 711 from 742 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
310 divided by 79 is 3 with a remainder of 73.
The number 3 becomes the next digit in our result. 
Result so far: 5189.3
Subtract 237 from 310 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
If we divide 730 by 79, we get 9 and a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 5189.39
Subtract 711 from 730 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 9:
When dividing 190 by 79, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 5189.392
Subtracting 158 from 190 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
320 divided by 79 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 5189.3924
If we take 316 away from 320, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
If we divide 40 by 79, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 5189.3924
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
400 divided by 79 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5189.392405
Subtract 395 from 400 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
79 can be fit into 50 0 times, resulting in a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 5189.392405
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
79 can be fit into 500 6 times, resulting in a remainder of 26.
The next digit of our result is 6. 
Result so far: 5189.39240506
Deduct 474 from 500 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 5189.39240506 and a remainder of 2.6e-08.
